In the field of modern sound engineering, line array (Line Array) systems have become the preferred sound solution for large-scale events and professional venues due to their superior sound quality and coverage capabilities. In this paper, we will discuss in depth the basic concept of line arrays, working principle and its application in audio engineering.

To reasonably configure the power amplifier and speakers, two issues must first be clarified, one is the natural properties of the music signal, and the other is the nature of the output power of the power amplifier.

Gain is one of the main indicators of the power amplifier. It is the product of the direction coefficient and efficiency, and it is the performance of the antenna radiation or the size of the received electric wave. The choice of gain size depends on the requirements of the system design for the radio wave coverage area. Simply put, under the same conditions, the higher the gain, the farther the radio wave propagation distance will be. The larger the receiving gain value of the power amplifier, the stronger the receiving performance.

Professional Amplifiers In terms of their main use, power amplifiers can be divided into two main categories, namely dedicated power amplifiers and civilian power amplifiers. Power amplifiers used in stadiums, movie theaters, dance halls, conference halls, sound reinforcement in public places, and recording monitors generally have some unique requirements on their technical parameters. a power amplifier or professional power amplifier.
